On Demand Content

This is another area of the website that  will likely be in a continuing state of development.   The concept for this section is to provide narrated slides that present basic principles that will help people learn general HVAC and building system concepts and will support and complement some of the other content on the site.   Most of the topics have been split up into 20-30 minute sections so that you can watch one of them on a break or while you are having lunch.

Induction Motors

The content on this section was originally developed to support the Design, Performance and Commissioning Issues class series at the Pacific Energy Center.   There are several videos that were also developed in conjunction with this content to demonstrate basic induction principles that you can access from the video page of the website.

 Functional Testing

These videos introduce the concept of functional testing, including contrasting how it is used in NCx vs EBCx processes.  They conclude with a case study for an EBCx project to illustrate how we wrote a test to ask the building a question, which led to a solution that solved an operational problem and opened the door to energy savings as well.

Scopes of Work 

This video provides an overview of what you might want to include in scope of work document supporting an EBCx project implementation.   It uses the addition of a more efficient evaporator pump to the Hijend Hotel central chilled water plant as the basis of discussion and includes an overview of the pump optimization options that were explored and how the decision to add a pump was made.

Loads and Psychrometrics

These videos are intended to help you learn about the HVAC loads, load profiles, psychrometrics, the psych chart and how to use it.

System Diagraming

These videos target helping you understand the system concept, in particular, how it is reflected in a system diagram.  They include two videos that introduce the concept, one video about hand drawn symbols and system diagrams, and one video where I use the Hijend Hotel central plant model to show you how to go about developing a system diagram in the field. Links to many system diagram resources are provided including the system diagram symbols tool page of this website.

Benchmarking, UCA, and Scoping

This video introduces the concepts of  benchmarking, utility consumption analysis, and scoping, all of which are important EBCx, ongoing Cx, operations, and building systems diagnostics and troubleshooting.  It includes links to resources and also a quiz you can take to test your new found knowledge.
